A= adult
C= child

3A+C = 38.3
A+3C = 52

There is no logical way to find the value of each other than guess-and-check.

What is the y-intercept of the line shown below? <br> A. 5<br> B. -5<br> C. 2<br> D. -2

lys-0071 [83]

Answer: -2

Step-by-step explanation: The y-intercept of a line is the point where the graph crosses or intersects the y-axis.

In this case, the line crosses the y-axis 2 units down from the

origin and we can write the coordinates of the point as (0, -2).

So the answer is -2.

Find the lateral and surface area of each cone

Sophie [7]

Answer:

$\large\boxed{L.A.=153\pi\ mm^2}\\\boxed{S.A.234\pi\ mm^2}$

Step-by-step explanation:

The formula of a lateral area of a cone:

$L.A.=\pi rl$

r - radius

l - slant height

The formula of a surface area of a cone:

$S.A.=\pi r^2+\pi rl$

We have r= 9mm and l = 17mm. Substitute:

$L.A.=\pi(9)(17)=153\pi\ mm^2$

$S.A.=\pi(9^2)+153\pi=81\pi+153\pi=234\pi\ mm^2$
